Originally, I was fishing around to see if I should get a mesh or solid loop-loc type cover for a new pool. I just met with a very respectable company that really only services commercial pools and opens and closes residential pools. They suggested I don't do a cover at all. Here are their thoughts.
1) I live in a new neighborhood, carved out of farmers fields and really don't have any trees within 200ft of my pool.
2) I have a high fence (5 ft) surrounding the pool and the gates have the ability to be locked.
3) I have a very free form sport pool with continuous curves that varies from 8 ft wide to almost 30 ft wide.
4) 25 ft of my edge are large boulders with a slide coming down the middle
5) All my deck surface is 12x12 pavers.
Because of these items, the install would be complicated. There would also have to be aluminum tubes drilled into the pavers which likely would cause some cracking and with the freezing and movement of pavers, will be a continual maitenance nuisance.
This person's suggestion was to simply to close in mid-November (live in MD) and then re-open April 1. About once a month during the winter, add some shock and scoop out any debris. The only issue is safety but if I am comfortable locking the gates and keeping the pool area off-limits (which I can do), then it's not a big issue.
Is this a crazy thought? I guess I just assumed you needed a cover.
